Select a hand tool (4)
I believe the answer is:
pick
I believe this clue is a double definition.
'select' is the first definition.
(picking is a kind of selecting)
'a hand tool' is the second definition.
(pick is a kind of hand tool)
(Other definitions for pick that I've seen before include "it for breaking up the soil" , "Select - ground breaker" , "Select - implement" , "Play guitar" , "Choose, select" .)
